The pruning stuff looks great, at the moment the time it takes to download the blockchain (and the disk space requirements to a lesser degree) is creating a disincentive to run a full verifying node.

I suspect bitcoin blockchain transactions will never be very useful for micro payments, because of the confirmation delay.

If you use bitcoin as a clearing house though, which means you aren't broadcasting a blockchain transaction for every payment then micro transactions could work very well.
